Question: Do Axolotl Females go through the menstrual cycle?

[MiseryInc]

Hey everyone,

So I did an all nighter playing computer games and at 8 am the next morning, I was looking at my axolotls - two females - and one of them was secreting a brownish liquid.

This wasn't poo. I'm quite sure. Their poo's are always left in a pile, but this one was sort of dissipating all over the tank and was a sort of "oily" substance on the bottom.

I'm only feeding them worms and about 6-7 of them a day - small worms. My axies are growing and they've had no problems at all since I got them - bar the tank breaking; twice.

So, could this be blood? Is Whooper on her period? I know that males have spermopheres whereas females lay eggs, but do they also secrete blood like on the human and most animal menstrual cycles?

Female axolotls carry their eggs at all times until they pick up a spermatophore; in that case they will lay them after fertilization and take some time to make more eggs after the laying.

They don't have their periods. Periods are related to mammals, not amphibians. Sometimes though, they can have some trouble digesting something, or something digested too fast, or something along those lines... and their poop can vary. Usually it's quite hard and in a little turd shape, but sometimes it can be more... loose. Depends on what they ate as well.

As Tephra has touched on, menstruation is exclusive to mammals, specifically, placental mammals. Without a uterus and a placenta, there can be no period.
Your animal was most likely discharging some left-over feces.
